This is an debombed (NOT official) ISO of Windows 8 build 8102 EEAP. You can activate and customize it just fine.
Thanks to Discord user "scamdisk" for the debombing steps.
Some notes:
Since this is an EEAP build, there is no Metro UI.
Due to the debomb method used, the branding will be Windows 8.
You can change it back using the basebrd.dll.mui (goes into C:\Windows\Branding\basebrd\en-us) and shellbrd.dll (goes into C:\Windows\Branding\shellbrd)
When it asks you for a product key, use a Windows 8 Enterprise generic key
